Answer 1

It’s a valve on the air intake that regulates how much air gets injected into the combustion chamber along with the fuel. When the engine is cold you want more fuel and less air because it’s harder for the fuel to turn into an aerosol when it’s cold. As the engine heats up it’s more efficient to use more air.
